  1. The resulting bogus contents of the array thwarts part of

  2. The resulting array is only 7 elements long (auto-sized), while

  now marked '<thread>' in the top(1) display.

* cleanup manipulation of COMMAND strings, insipired by a
  similar change in NetBSD's top(1).

* add a toggle for system processes, called 'S' so we dont
  need to restart top(1) to {un}display system processes.

* change some sprintf's to snprintfs for safety.

* update the sort/ordering top(1) commands so that it correctly
  displays kernel threads by priority time used etc.

* add a 'thr' sort order function so that kernel threads can be
  collected together in the top(1) display; this is useful when
  running it in batch mode.

* fix the screen width issue for terminals that have more than
  80 columns; this was necessary for showing threads properly in
  SMP mode.

* add ability for top(1) to sort kernel threads their priority
  (note, thread priorities are stored differently).

NOTE! top(1) is now using the contrib-patching framework just like

in the future if required.
